Elisabeth of Hesse Kassel, wife of Prince Otto of Hesse, youngest son of the late Philipp and Mafalda, passed away a few days ago. Elisabeth & Otto married on December 28, 1988 and Otto died in 1998. Elisabeth was born Elisabeth Bönker in 1944 at Rumburg, Czechoslovakia. She was Otto's 2nd wife and they had no children.
I saw one site saying they divorced in 1994 but Otto's siblings Moritz and Elisabeth are listed on the funeral card as the chief mourners with the service at Schloss Friedrichshof which would seem strange in that case.
